The award-winning seven-passenger GL-Class-the first full-size SUV from Mercedes-Benz-gets a timely new model for 2009.  Joining the fully equipped, 382hp GL550 model and the highly successful GL450, the fuel-sipping GL320 BlueTEC diesel features a new AdBlue exhaust treatment system that helps it meet the most stringent 50-state emissions limits.

The GL320 BlueTec is changing consumers’ dated perceptions about today’s diesel engines-it gets surprisingly good performance, very quiet running, and extremely low exhaust emissions, in the process of delivering 20-30% better fuel economy. With an EPA highway fuel mileage rating of 23mpg/highway, 17mpg/city, the seven-seat SUV boasts an impressive cruising range of up to 600 miles at highway speeds.  With V8 like pulling power the GL320 BlueTec can tow up to 7,500lbs. with the optional Class IV trailer hitch.

2009mercedesbenzgl320bluetecbadge01smallBlueTec is a modular system that includes an oxidation catalyst and a maintenance-free particulates filter as well as new techniques for reducing nitrogen oxide emissions-the last type of exhaust gas that’s higher in diesel vehicles than gasoline engines.  The BlueTec diesels use an NOx storage converter in combination with an SCR catalytic converter and AdBlue injection to lower NOx emissions.  The AdBlue system (technical name: urea SCR system) injects an aqueous carbamide solution into the exhaust flow, which releases ammonia reducing nitrogen oxides to harmless nitrogen and water in the downstream SCR converter.  Just the right amount of AdBlue for a given engine load and speed is injected to get the greatest reduction in nitrogen oxides.  On average, only a quart of AdBlue is needed for every 600 miles driven, so its tank only needs to be serviced every 10,000 miles as a part of regularly scheduled maintenance.  BlueTEC owners who are used to taking in their car for scheduled maintenance will hardly know the AdBlue tank is there.

2009mercedesbenzgl320bluetecengine01smallThe diesel-powered GL320 BlueTEC all-aluminum, 3.0 liter DOHC 24-valve turbocharged V6 engine delivers impressive performance, low exhaust emissions and great fuel economy.  With 210hp and a healthy 398lb.ft. of torque, the GL320 BlueTEC features an innovative V6 diesel engine with the torque of a V8 and the fuel economy to rival some four-cylinder engines.  Equipped with the latest CDI (common rail direct injection) technology, this electronically injected diesel engine is changing consumers dated perceptions about diesels.

Mated to this high-tech engine is Mercedes-Benz advanced 7-speed electronically controlled automatic with Direct Select and driver-adaptive shift logic 4MATIC permanent AWD transmission 2009mercedesbenzgl320bluetecpanleft01smallthat drives all four wheels.  You also have the option of holding down the shifts with paddle shifters on the steering wheel.

Underpinning the new GL320 BlueTEC giving you a smooth controlled ride is 4-wheel AIRMATIC air suspension with a double control arm front suspension with air springs, gas shocks and stabilizer bar.  The rear features four-links, air springs, gas shocks and stabilizer bar.  Optional is ADS adaptive damping front and rear.  Comfort or Sport mode can be dialed in by simply pushing a button on the lower center stack.  A thick strut tower brace up front ensures quick response handling and steering dynamics at high speed.

Quickly slowing this heavy sport utility down from speed are very large vented steel disc brakes, 14.7in. up front, clamped by dual-piston calipers, and 13in. rear discs clamped with single-piston calipers.  Keeping you in control is standard ABS and Brake Assist.

The GL320 BlueTEC rides on giant 20X8.5in. front and rear aluminum wheels that are wrapped with Goodyear 275.50R20in. all-season radial tires.
